"If S. everetti is a smaller race of S. lempiji it is hard to understand the above measurements. We were at first inclined to identify our Palawan specimen with the latter species, but after comparison with Dr. Steere's specimen of S. everetti from Samar, find ourselves unable to do so." (Bourns and Worcester MS.) 211. OTUS FULIGINOSUS (Sharpe). PALAWAN SCREECH OWL. Scops fuliginosa Sharpe, Ibis (1888), 197; Hand-List (1899), 1, 287. Scops everetti Whitehead, Ibis (1893), 44. Otus fuliginosus McGregor and Worcester, Hand-List (1906), 46. Palawan (Whitehead). Diagnosis.--Similar to Otus umbratilis but much smaller, and entirely rich brown; vermiculated and spotted as in typical Otus but auricular region uniform rufous-brown; and with frontal and cervical bands pale and obsolete. [28] Whitehead, who collected the type, refers this species to Scops (=Otus) everetti and says: "I find that Mr. Sharpe has not much faith in his Scops fuliginosa, which in all probability is only the young of S. everetti." Sharpe retains the species in his "Hand-List" and therefore it is given here. 212. OTUS SIBUTUENSIS (Sharpe). SIBUTU SCREECH OWL. Scops sibutuensis Sharpe, Bull. Brit. Orn. Club (1893), 2, 9; Ibis (1894), 244; Hand-List (1899), 1, 287. Otus sibutuensis McGregor and Worcester, Hand-List (1906), 46. Sibutu (Everett). Diagnosis.--Similar to Otus mantananensis but upper side of wings scarcely spotted with white and quills but faintly banded below. "Bill blackish brown; feet brown; iris yellow." (Everett.) Length, 203; wing, 152. [29] Everett collected an adult male and female and a young bird in Sibutu. Sharpe makes the following observations: "This race is intermediate between S. menadensis [from Celebes] and S. mantananensis [from Mantanani Island, Borneo] which I described last year; the white wing markings, however, are altogether smaller and not so distinct, the under surface of the quills being almost devoid of markings. From S. menadensis the Sibutu bird differs in having all the markings of the upper surface very fine and not all over as in that species. The quills have also more bars in the Celebean bird than in the species from Sibutu." 213. OTUS LONGICORNIS (Grant). LONG-HORNED SCREECH OWL. Scops longicornis Grant, Bull. Brit. Orn. Club. (1894), 3, 51; Ibis (1894), 504; (1895), 439; Sharpe, Hand-List (1899), 1, 287; McGregor, Bull. Philippine Mus. (1904), 3, 7. Otus longicornis McGregor and Worcester, Hand-List (1906), 46. Bang-aó, Benguet. Luzon (Whitehead, McGregor).
